Parking9 Warning
● Do not park the vehicle on an
easily ignitable surface. The
high temperature of the
exhaust system could ignite the
surface.
● Always apply parking brake without pressing release
button. Apply as firmly as
possible on a downhill slope or
uphill slope. Depress brake
pedal at the same time to
reduce operating force.
● Switch off the engine.
● If the vehicle is on a level surface or uphill slope, engage
first gear. On an uphill slope,
turn the front wheels away from
the kerb.
If the vehicle is on a downhill
slope, engage reverse gear.
Turn the front wheels towards the kerb.
● Close the windows.
● Remove the ignition key from the ignition switch. Turn the
steering wheel until the
steering wheel lock is felt to
engage.
● Lock the vehicle by pressing e on
the remote control 3 26.
Activate the anti-theft alarm
system 3 38.
● The engine cooling fans may run
after the engine has been
switched off 3 168.
Caution
After running at high engine
speeds or with high engine loads,
operate the engine briefly at a low load or run in neutral for approx.30 seconds before switching off, in
order to protect the turbocharger.
Vehicle storage 3 167.
Driving and operating141Engine exhaust9Danger
Engine exhaust gases contain
poisonous carbon monoxide,
which is colourless and odourless and could be fatal if inhaled.
If exhaust gases enter the interior
of the vehicle, open the windows.
Have the cause of the fault
rectified by a workshop.
Avoid driving with an open load
compartment, otherwise exhaust
gases could enter the vehicle.
Diesel particle filter
The diesel particle filter system filters
soot particles out of the exhaust
gases. The system includes a self-
cleaning function that runs
automatically during driving without
any notification.
The filter is cleaned by periodically
burning off the soot particles at high
temperature. This process takes
place automatically under set driving
conditions. Autostop is not available
and fuel consumption may be higher
during this period. The emission of
smells and smoke during this process is normal.
Under certain driving conditions, e.g.
short distances, the system cannot
clean itself automatically.
If cleaning of the filter is required and
if previous driving conditions did not
enable automatic cleaning, it will be
indicated by the illumination of control
indicators j 3 99 and Z 3 99 in the
instrument cluster. Seek the
assistance of a workshop
immediately.Caution
If the cleaning process is
interrupted, there is a risk of
provoking severe engine damage.
Cleaning takes place quickest at high engine speeds and loads.
Catalytic converter
The catalytic converter reduces the
amount of harmful substances in the
exhaust gases.Caution
Fuel grades other than those listed on page 3 161 could damage the
catalytic converter or electronic
components.
Unburnt fuel will overheat and
damage the catalytic converter.
Therefore avoid excessive use of
the starter, running the fuel tank
dry and starting the engine by
pushing or towing.
In the event of misfiring, uneven
engine running, a reduction in engine performance or other unusual
problems, have the cause of the fault
rectified by a workshop as soon as
possible. In an emergency, driving
can be continued for a short period,
keeping vehicle speed and engine
speed low.

Driving and operating145Refilling AdBlueCaution
Only use AdBlue that complies
with European standards
DIN 70 070 and ISO 22241-1.
Do not use additives.
Do not dilute AdBlue.
Otherwise the selective catalytic
reduction system could be
damaged.
Note
If AdBlue must be refilled at very low temperatures, the refilling of AdBlue
may not be detected by the system.
In this case, park the vehicle in a
space with a higher ambient
temperature until AdBlue is
liquefied.
Note
If engine starting is prohibited due to low AdBlue level, we recommend
refilling the tank completely or with a volume of at least 10 l of AdBlue
(depending on AdBlue
consumption).
Avoid minor top-ups (e.g. less than
10 l), otherwise the system may not
detect a refill.
Note
When unscrewing the protective cap from the filler neck, ammonia fumesmay emerge. Do not inhale as the
fumes have a pungent smell. The fumes are not harmful by inhalation.
The vehicle must be parked on a level surface.The filler neck for AdBlue is located
behind the fuel filler flap, located on
the left-hand side of the vehicle.
The fuel filler flap can only be opened
if the vehicle is unlocked and the left- hand door is opened.9 Danger
Vehicles with stop-start system:
The engine must be switched off
and the ignition key removed, to
avoid risk of engine being
restarted automatically by the
system.

assistance of a workshop
immediately.
4. Open AdBlue canister.
Driving and operating1475.Mount one end of the hose on the
canister and screw the other end
on the filler neck.
6. Lift the canister until it is empty, or
until the flow from the canister has stopped. This can take up to
5 minutes.
7. Place the canister on the ground to empty the hose, wait
15 seconds.
8. Unscrew the hose from the filler neck.
9. Mount the protective cap and turn
clockwise until it engages.
10. Close fuel filler flap and left-hand door.
Note
Dispose of AdBlue canister
according to environmental
requirements. Hose can be reused
after flushing with clear water before AdBlue dries out.
Note
Allow the vehicle to idle for at least
ten seconds to allow the system to
detect the AdBlue refill.Failure to observe this procedure will
result in the system only recognising the AdBlue refill after approx.
20 minutes of driving.
If the AdBlue refill is detected
successfully, AdBlue level warnings
will disappear.
If the AdBlue refill is not detected
some time after running the engine,
seek the assistance of a workshop.
Filler cap
Only use genuine filler caps. AdBlue
tank has a special filler cap.
Fault
If the system detects an operating fault, control indicator Y illuminates
together with j and a warning
chime. Seek the assistance of a
workshop immediately.
A corresponding message appears in
the Driver Information Centre 3 103.Manual transmission
To engage reverse, with the vehicle
stationary depress the clutch pedal, pull up the collar on the selector lever
and engage the gear against the
resistance.
If the gear does not engage, set the
lever in neutral, release the clutch
pedal and depress again. Then
repeat gear selection.
Do not slip the clutch unnecessarily.
When operating, depress the clutch
pedal completely. Do not use the
pedal as a foot rest.
148Driving and operatingCaution
It is inadvisable to drive with hand
resting on the selector lever.
Gear shifting 3 100.
Stop-start system 3 137.
Brakes
The brake system comprises two independent brake circuits.
If a brake circuit fails, the vehicle can
still be braked using the other brake
circuit. However, braking effect is
achieved only when you depress the
brake pedal firmly. You need to use
considerably more force for this. The
braking distance is extended. Seek
the assistance of a workshop before
continuing your journey.
When the engine is not running, the
support of the brake servo unit
disappears once the brake pedal has been depressed once or twice.
Braking effect is not reduced, but
braking requires significantly greater
force. It is especially important to bear this in mind when being towed.
If control indicator R illuminates in
the instrument cluster while driving
and a corresponding message
appears in the Driver Information
Centre 3 103, there is a fault in the
braking system. Seek the assistance
of a workshop immediately.Control indicator R 3 99.
Vehicle messages 3 104.
Antilock brake system Antilock brake system (ABS)
prevents the wheels from locking.
ABS starts to regulate brake pressure
as soon as a wheel shows a tendency to lock. The vehicle remains
steerable, even during hard braking.
ABS control is made apparent
through a pulse in the brake pedal
and the noise of the regulation
process.
For optimum braking, keep the brake
pedal fully depressed throughout the
braking process, despite the fact that
the pedal is pulsating. Do not reduce
the pressure on the pedal.
After starting-off, the system performs a self-test which may be audible.
